| 摘 要： | k是M-自然类,证明在k中,任意M-内射模的直和的基本扩张是M-内射模的直和,并且通过可数多个k-cocritical模,刻划了∞i=⊕1E_M(S_i)的基本扩张是M-内射模的直和.

| Abstract: | In this paper we show that essentiality of direct sums of any M-injective modules belonging to natural class κ is direct sums of M-injective modules and essentiality of estensions is the direct sums of M- injective modules characterized by a countable k-cocritical modules. |
